Highly unlikely, the 128x84 KS0108 displays cannot normally be directly driven as you have to connect up the negative voltage supply to the contrast pot among other things. So you will need a breadboard or a shield specifically designed for it.

Exactly, that's why I am using the LCD-Keypad shield. The only difference is that the (128x64) needs extra 4 pins that can be re-routed on the shield.Not a biggie.

There are at least 3 different pin mappings on 128*64 displays. Please read the link I posted. I warn you not to use your shield on the dot matrix display. You could be shorting 5V with GND if the pins are not compatible. You will need to suffer with jumper wires unless someone has made a shield for it (maybe). ]

BTW, I have my own character LCD shield, it's just more awesome,IMHO, with RTC, EEPROM, and GPS etchttp://liudr.wordpress.com/phi-1-shield/

Right now, I'm making a project involving a ks0108 display where saving up is really important. Since I wanted to use a 328, and still use some pins, I've set up an ATMEGA8 (7.somthing Kb of free space) on a breadboard, and uploaded to it a simple code with the library and a serial communicacion protocol, to interface with the Duemilanove (the one that makes all the calculus and reads the sensors). It works great, at this very moment I'm looking at it, and it's displaying a real-time sinus wave generated by the own ATMEGA8, so so far it doesn't seem to be too slow.

The first one is the Atmega8 attached to the GLCD, the next is the same, but with the Duemilanove (working as a power supply), and the last one shows how using the 2009 as GLCD "driver" makes pins disappear.

It's quite straightforward to do this: burn bootloader into atmega8, upload the sketch using the FTDI chip, wire up, and see how the sine is generated

EDIT: does anyone know how to reduce the size of the images on the forum?

Thanks for the compliments. Right now dipmicro.com is selling my shield. They have all the parts the shield needs at a low low price. I can't find anywhere else with all those parts.

mrquesito,

That's awesome. Here is one Karma! Waiting for codes. Have you considered buying an RBBB PCB and mount everything nicely together? Here:http://shop.moderndevice.com/products/rbbb-pcbI just bought 5 of them
